The search for magnetic fields in mercury-manganese stars
V. Makaganiuk, O. Kochukhov, N. Piskunov +7
We performed a highly sensitive search for magnetic fields on a large set of HgMn stars. With the aid of a new polarimeter attached to the HARPS spectrometer at the ESO 3.6m-telesc…
The HARPS polarimeter
Frans Snik, Oleg Kochukhov, Nikolai Piskunov +8
We recently commissioned the polarimetric upgrade of the HARPS spectrograph at ESO's 3.6-m telescope at La Silla, Chile. The HARPS polarimeter is capable of full Stokes spectropola…
Least squares deconvolution of the stellar intensity and polarization spectra
O. Kochukhov, V. Makaganiuk, N. Piskunov
Least squares deconvolution (LSD) is a powerful method of extracting high-precision average line profiles from the stellar intensity and polarization spectra. Despite its common us…
Doppler images of the RS CVn binary II Pegasi during the years 1994-2002
Lindborg, M., Korpi +8
We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. The six maps from 1999-2002 are based on previously unpublished observation…
